i think there can only be defaults if all parameters are default
( at a new clean install from scratch )

cause there are depencies, so if you change one parameter ,others might
be changed too, at last ,using distro packs, may also change default
setups to what the distro releaser means that is best, so Timo might not
the right man ,to talk to in such case...

perhaps others might mean the better way is to let dovecot start with
warning and let it crash later....

i think in this case ,there is no "make all people happy" chance

so the only problem might have been not reading changelogs or/and better
anouncement to new stuff,

lucky Timo is patching fast and quick, on the other Hand people
arent that quick as Timo *g, so everything has its pros and contras
perhaps it might be better to have a devel tree, but as far i see
Timo is the main coder so its definite up to him how to handle
releasing, unless there are no other prime coders to which he has
to sync, and i think Timo would be happy if there would be more heavy
coders at dovecot for better testing,releasing,coding etc

but after all its not a heavy problem,
there might be always trouble with latest code so be prepared at
upgrade, make sure that you can get back at productional

why no use something like i.e default_vsz_limit = 256M ?
instead of using seperate entries

Best Regards
