I'm aware of this theoretical conflict. But I see the risk as very low
compared to the value of not having to make a lot of customizations for
export and internal link handling. It should just work out of the box.

If you deem necessary there would still be the possibility to define a
global switch for this. This could then still have the 100% save default,
while still being easy to "configure".

If you want to go so far you could mitigate the risk of a conflict by
"escaping" the macro brackets. {{{{{{not-a-macro}}}}}} would be treated as
{{{not-a-marco}}} without expansion. Or any other escape sequence to bring
the conflict probability to 0.0000001.
