So if you get a binary package, you will not get debug symbols, even if that setting is on on your system. You will only get debug symbols if the port, for whatever reason, builds from source on your system. That would be confusing. Therefore, so that you get consistent behavior, if we introduce such a new setting, it must also prevent all use of binary packages.

I understand, and that's besides the point for now. Would we be
generally okay with adding a new option to add -g globally?  Perhaps
include_debug_symbols true.

This ought to have three effects
(a) include -g
(b) exclude strip(1)
(c) port specific changes at their option

this ought not to change optimization or related.
