Can't \e be used instead?

    .ds x \e
    .ds y @
    .ec \*[y]
    escape char is @e
    .ec \*[x]
    escape char is \e

Why the special commands?  Are you worried about not knowing the
current escape character when you want to save it?  If so, isn't just a
convention that it is always backslash when source macro packages, etc.
If you change it locally you should change it back before using others
code.

I'm after a little more understanding as to why new commands are
necessary.
