My idea was that it would make things easier on 1.7 down the road, when
we have both ncurses and ncursesw, but only the one tinfo.

For a survey of linux to make sense, you have to exclude those which
ship only 5.6 and older -- which is quite a few; there was no tinfo
option then.  However, in my survey I find only one distro -- PLD --
that splits tinfo into a separate library, yet (almost) all of them ship
both narrow and wide versions of ncurses.  And PLD had to modify their
vim configury to use --with-tlib='ncurses -ltinfo'.

Both points reinforce your argument.

Now, I would just say: "Well, maintainers ought to use the handy new
ncurses9-config script, or even the new pkginfo, which are now supplied
with ncurses5.7."

But I can't say that, because they're borked.  They are apparently
ELF-only, as they do not list the dependent libraries.  That is, for
win32, the ncurses++.pc file ought to list '-lncurses++ -lpanel -lform
-lmenu -lncurses' (and maybe also -ltinfo, depending on the
configuration), not just '-lncurses++ -lncurses'.

Stay tuned for 5.7-3/5.7-12. Sigh.
