I don’t think so.
In some cases you may not get the ligature for a good reason:
\starttyping
program --option=value file.ext
\stoptyping
It would make no sense to get an en-dash there (but I guess you don’t
mean that).
But all OSes provide character maps to get single characters. And also
Unicodia works fine in Windows (https://mercury13.github.io/unicodia/,
just in case it might suit your needs).
Having a single character (emoji, dashes or whatever) is way more
readable than a character combination for a ligature or a TeX command.
This single-character approach also makes easier to copy and paste text
to other formats.

Just consider that you should add an horizontal box (or pair both space
and hyphen), otherwise you may get a line break between character and
hyphen (instead of the hair space):
\starttext
\startTEXpage[offset=2st]
\hsize\zeropoint
this —\hairspace or so\hairspace— that
this \hbox{—\hairspace}or so\hbox{\hairspace—} that
\stopTEXpage
\stoptext
Just in case it might help,
Pablo
