1/ Well, than we can argue that Sanctionated Psyker. Tech-Priest, Commissar and Priest have no position to be permanently in regular squad as their callings are not exactly frontline (ok, with exception of Commissar, but than, why should he be attached to one squad all the time?). And that Stormtroopers, Ratlings and Ogryns would work best in dedicated squads. That´s why they are Support Specialists. Heck, without fluff in Beta we don´t know if we will be only playing the regular squad, but I personaly doubt it. There are uncountable examples in 40k fiction of specialist groups or irregular squads even from mundane regiments, which would be intresting to roleplay. Last Chancers, Tanith (Vervunhivers, Belladons, some local priest guy, oh and missions with other regiments), Redemption Corps from the novel of same name, search party in Ice Guard, Detachment 99 from Imperial Armour IV Anphelion Project, deathsquad of stormtroopers, Inteligence Officer and Eversor in IA3: Taros Campaign, concept of kill-team in general as presented in WH40k 4th Edition Rulebook…

2/  I see your point with Pathfinder, Toughness it is. Yeah, I understand, but as Weapon Specialist does not  represent just some regular grunt or operator isn´t some generic driver, I intented the Whiteshield not to be just a representation of  some new guy, more of something like a charm and lucky guy, along the ways of Brin Milo from GG, or even Lieutanant Sulla from CC (altough she is slightly more insane…)

Sanctioned Psykers and Tech-Priests tend to be second-line but will move to the frontlines as situation requires, while the Comissar and Priest's jobs are in the thick of the fight, emboldening the troops and keeping the line. Also, at least in 4rd Ed., all those classes could be attached to an infantry squad, effectively forming part of it. The Comissar is assigned to… oversee the Sergeant, the Priest decides to make the squad the Emperor's chosen vessel for His word, Command assigns the squad to "escort" one of their most talented psykers (whether it's because they consider him too valuable an asset to risk or because they don't trust a standard 4-man escort to keep him in check is up to debate) and who knows what arcane calculations drove the cog-head to believe joining the squad was the most optimum use of his talents? He's tagging along anyway.

The common denominator is that they're all fighting men in the Guard. True, sometimes you can get the aid of some irregulars, but in almost all of the examples you mentioned the irregulars stayed until the crisis was averted and then parted to never again cross paths. If you're doing a one-shot campaign then that's fine, but if you plan on dragging your players along several campaings and different operational theaters, then the only suitable classes are those that'll stick around through thick and thin because, at the end of the day, they're all brothers in arms.

Don´t own the book but IIRC mission to kill Tau Commander and Ethereal was after Operation Comet but before big Tau push, and it is presented both in fluff and mission sections, hope it helps.
