Soften messages for read-only extensionsDir
Improve messaging when someone has a different policy for managing extensionsDir
.This a continuation of this PR. Most of the messaging update has already been done. There is only one message ("Read-Only Extensions"). It still encourages web-writable policy, but it lowers the severity and presents it a choice ("if you want X, do Y").
Probably, changing the warning
into a notice
is the only thing to update:- a warning
implies something is wrong, while a notice
says it's merely out of the ordinary.
