I see termcap as a great solution for the days in which there was little
standardization. But it's probably pretty hard to find a non-conforming
terminal nowadays so I think that it's better to avoid obfuscation. Were
it me I would have a comment that referenced the page and section number
in the standard.
Since we like debating the merits of old technology, somebody can kick off
a termcap versus terminfo discussion :-)

I got to look at the source to a few other
editors of the era. All has
the terminal codes hard coded into them... it was common to do that
before things like termcap...
It's still common today. Everything the developer cares to think about,
let alone test on, interprets EMCA-48 SGR escape sequences. My favorite
recent example is "spectre-meltdown-checker", which has such edifying
lines as:
_info_nol "> \033[46m\033[30mSTATUS:\033[0m "
Why write something portable when you can be "close to the metal"? :-/
I gently steer people to better ways when the occasion presents itself.
