It is not completely clear from your message what the current behaviour
is and how texinfo.tex and texi2any differ. It would be more clear with
examples of input and how the proposed change affects what is done with
these examples.
One major problem with expansion on the @clickstyle line would be the
treatment of newlines in the expansion. In texi2any, I expect that
newlines would terminate the @clickstyle line:
@macro mac {}
@result
next line
@end macro
Then "@clickstyle @mac" would expand to
@clickstyle @result
next line
This is unlikely to be what happens with texinfo.tex and I would not
be surprised if it led to an error.
If, as you say, texinfo.tex expands the argument to @clickstyle at
a later stage, when @click{} appears rather than on the @clickstyle
line itself, that would seem like a pretty major difference from texi2any.
We should check that any supported use of macros with @clickstyle works
correctly with both processors.
