Possibly but it's at least a step in the right direction of letting M+ and raids both be valid yet independent end game group PVE activities.
An example (not thought through in detail so let's not nitpick...)
Wild Growth now hits 6 targets for 63% of spellpower within 30 yards of the caster. An M+ trait could enable WG to, say, increase the spellpower % or remove a debuff. A raid version could increase the range or the number of people affected.
Yes, there might be cases were someone really wants the M+ version for a given raid fight... and that's fine. They can choose to get it to help. But right now if you want good high level Azerite pieces you HAVE to raid, even if you really are only interested in M+ high keys.
