It would need to be something entirely different. Consider

condition = ${lookup ....}

There's no "if" involved there. "if" is only one feature of string
expansions. If you want to change to

condition = eq{string1}{string2}

then the whole rhs has changed its semantics rather drastically. It's
no longer a generalized expanded string, but some specific conditions.
For compatibility, one would need to have a different name, e.g.

iftrue = eq{string1}{string2}
