No, I'm guessing most of the FM3 crowd are people entirely new to the FAS ecosystem, so that thread served as an introduction on how FAS' updates are posted on the forum and to appease guys asking for updates pre 3.XX, back when there were many bugs pending...
I'd like to think that most of the Axe FX people (specifically in the forum) already knows that whenever a new FW gets released it gets a new thread sticky here. Also, it's worth mentioning that Public Betas are exclusively posted on the forum, and when it gets an Official Release it only gets posted on the main website until FAS considers it's stable and mostly bug-free.
Regarding new FW updates showing on Fractal bot, only Official Releases are pushed, Public Betas are only accesible via direct download through Cliff's posts on the forum.
