its code to handle possible aliases because "any tag you like"

with diaper=no + changing_table=yes
the only thing you can do with it is waste your time:
either by writing rules to say that a conflict between

or by spending time writing to the concerned contributors
to correct the inconsistency,
or by using one of the 2 values and then spending your
time debugging why the value is wrong 50% of the time
