Giving each job a second spec: would it work?

[Ashkendor]

So if Devs decide they don't like something - even if players request more of it because it's successful from a functional and practical use standpoint (SCH/SMN) - they shouldn't consider it?

Nope. If they don't like it, they're under no obligation to do it no matter how many players want it.

No I meant Scholar. Not Arcanist. Scholar is the healing spec, Summoner the DPS spec. The same Job otherwise - they share gear and levels, other than the weapon.

You said "Scholar has two specs", though. It doesn't. Arcanist has two specs, Scholar and Summoner.
