So if I do, I don't need to "package-require"
it in the commented package header? It
will be enough with just a `require'?
However since the "package-require" was
supposed to be transparent, and not download
anything unless needed, doesn't that amount to
- if I put it there - it will be installed on
< 25.1, but not installed on version where seq
is part of vanilla Emacs?
Or is this "in theory" only?

I think the last quote was a way of saying "it
is difficult" - which you and I don't agree on
anyway :)
But as for the build options, what options is
it that are difficult to understand?
They should be documented somewhere if they are
not self-explanatory or conventional enough -
there should be comments in code at the very
least. Try understanding them one by one
instead of grouping them together claiming them
beyond mere users. And if everything fails,
just use the default ones and be a happy Emacs
user ever ever :)

Yes, one :) And not just anyone, either :))
