whatever choice you make, there will always be people that find this unexpected.

just think about all the "bio-people" that will have their water
molecules "chopped"
when you make -nocompound the default (and complain about it).

it is the privilege of the maintainer of a package to choose.

BTW, it may be convenient to include an -updatebonds (default off) flag
that will call 'mol bondsrecalc <mol>' after the (final) wrap.
