I saw it exactly like that that's why it would make me have to do one extra upload and one extra manifest editing at each DLC.

I don't get how exactly Baertram avoid this unless he manages to slip it into a bugfix that would occur after his PTS tests. But I nvm. I get it that it's useful for the people who use it, I just don't have the same point of view, I tend to take into account the lamba user/lambda author faced with the choice to use it or not

and beside, in a general way, I don't want my files to be edited without my consent. It can make troubleshouting harder in general and in this very case, it obfuscates to the user if he did or not do the update already especially if he does his updates manually without Minion.
(I personaly would be that user and as it, not seing an advantage in being able to use fastAPI on untagged files at all)
