It doesn't have to be always true, just sometimes true, for a warning
to be prudent.

I am not going to split hairs with you nor play he-said-she-said. The
combination of KDE (this is a KDE-centric list) and ext4 (the new
shiny filesystem in this list's focus) is dangerous today.

There are advantages, but "very compelling"? Which advantage would you
call "very compelling". Furthermore, I agree about "appropriate time"
but now is not appropriate time.
