Well, it may not be equivalent, depending on the macro. Also, this is
not the point. \alpha{{{macro(arg)}}} is valid, so we have to parse it
as something. In this case, there are two possible interpretations.
I want to avoid it.

Macro expansion only happens at the beginning of the export process. The
problem you want to solve isn't necessarily tied to the export
mechanism.

Also, as you mention "latex-or-entity", which doesn't exist anymore, you
should look at the parsing code in master instead of maint, in
particular to `org-element-latex-fragment-parser'. Maybe the mechanism
used to find a macro can be improved to match more of them without
matching anything else.
