most of what you say about externals vs libraries is certainly true (see
i wasn't arguing about the pros and cons of your build-system which
certainly has its merits.
what i didn't like is the attitude of saying more or less "by using
libraries you hinder collaboration", implying that developers doing so
are second class coders and a disgrace to the entire free software

that one again... i mean it doesn't really avoid nameclashes, it just
shifts the decision away to some supervisor who decides which library's
object will get included; and most often this decision will be based
(note: i am wildly assuming things here) on bias (because the one who
has written the external adds it to the built system), on time (when did
the supervisor first noted that a certain object exists and it could be
added to the built system; this does not necessary mean that it really
was the first (publically available (e.g. sourceforge-cvs)) object with
this name), on discrimination (objects that are (for whatever reasons)
part of a library will not get included; if someone later on decides to
write a object with the same name as an external it will get included)

i don't think that this is necessarily a bad thing.
i rather prefer a mail client that does not enable every possible
feature (with bells and whistles and everything) by default.
there are objects in the current built system which have severe bugs
that make pd a crashy experience. often i do not have the time,
permission or knowledge to solve such bugs.
