no need to use [declare -stdlib/-lib], this woks if there is a compiled

this is not true for every library.

 distributing externals along with an abstraction is bad form like you
said, in my opinion

no reason to remove them, no technical issue, and you'd make a mess and mix
up all externals, which is bad

it is ok

it won't work with externals the user has installed... YET, see
https://github.com/pure-data/pure-data/pull/205

I dont understand this question
