I doubt we'll consider changing it.  If I haven't missed any of the
details, the critical points here are

(1) User names containing trailing (or embedded) spaces are legal.
    Not a very good idea maybe, but legal both per SQL spec and per
    our historical practice.

(2) Making ECPG strip trailing spaces would render it unable to
    connect as such a user.

I don't think ECPG has any business deciding that trailing spaces are
insignificant.  If that's the case in your application environment,
fine: strip the spaces at the application level.  But don't expect a
general-purpose library to make that policy choice for you.
