This UTR just addresses the case of a combining coloring symbol for faces
and those color symbols were designed since the begining to be combined as
much as possible (and not meant to be used in isolation), this is not the
case of the rainbow symbol which is much more figurative).
Why would associating a flag and a rainbow this way means the flag will
just be recolored (but the rainbox form itself is completely lost)?
Couldn't this be to display a flying flag over a sky with a rainbow?
Compare this to the association of the sun and the rainbow symbols, or the
cloud and a rainbow (and compare to the sun or moon and a cloud associated
the same way, or the association of two clouds: none of them will overlap
completely).
Imagine the use in a weather application, I don't wee why the rainbox would
disappear when the flying flag is just there to mean the windy condition,
and the rainbox meant for variable weather mixing rainy and sunny periods.
Your proposed use of ZWJ to create a complete overlap of one symbol into
another is unexpected.
ZWJ+symbol does not transfor that symbol into a "emoi modifier" (this is
not anywhere in UTF51). It may just create a small partial overlap of one
symbol into the other, but each one is still clearly identifiable
separately. The examples shown are for grouping multiple persons in Annex E
but each person is still separately visible and recognizable as such even
if they are combined in the same final glyph. Annexe E even requires some
specific orders (e.g. for families: the man can only come before a woman,
and is then necessarily visible to the left side of the icon, i.e. to the
right of the woman; children are necessarily after and below adults...).
