It seems to me that it would make sense to apply the same logic as
for "remote" augments to this rule - from RFC 7950:

    If the augmentation adds mandatory nodes (see Section 3) that
    represent configuration to a target node in another module, the
    augmentation MUST be made conditional with a "when" statement.  Care
    must be taken when defining the "when" expression [...]

I.e. the answer to your (original) question would in that case be
"yes" (at least for YANG 1.1 modules...).
