Will Beastmaster appear in any Endwalker content patches?

Chemist itself didn't kill Chemist, according to the devs. Ninja and the tentative plans for Machinist did, for having effectively taken its core gimmick (the 'mix' mechanic, which they had trouble imagining in form sufficiently distinct from mudras) and its core weapon theme (a sidearm gun).

That's a semantic argument, and my point wasn't even about what specifically killed Chemist, only that for some reason or other, they didn't get it in for Heavensward or Endwalker, not for lack of trying each time.

only if it sufficiently differentiates itself, which pretty much requires that the devs reverse their stance on homogeneity being the best thing since sliced bread.

... you're complaining about homogeneity in the same breath you point out that they chose not to go with Chemist because its core mechanic would have been too similar to an existing job's?

Yes. Because Mix and Ninjutsu need not have been "the same thing". Yet, to the devs, they were, just as Delirium and Inner Release have, to the devs, "necessarily" met at identical constructs with similarly near-zero interactions.

Meanwhile, if a grenadier-style toolkit and a machinist's were too similar in that they both used guns, the easy fix there would have simply been to share a base class, Gunner, and use split-exp jobs thereafter -- a correction they already should have applied to SMN and SCH. Alas...

That's a semantic argument

Not when your point was that Chemist was unfeasible regardless of context, when the devs themselves had said that, no, it was unfeasible primarily due to its context. That's not semantics; they're polar opposites.
