Well, first they’re not different mechanics. They’re simply the same mechanic with skill limits enabled or disabled. So it’s essentially the same as ticking ‘Not Created Equal’ on XCOM2’s Second Wave Options - ‘Do you want Rookies created randomly or not: Yes or No?’ - except in this case it’s ‘Do you want Skills to be limited or not: Yes or No?’
And secondly, would you rather that 30% of PP’s potential player base walks away and plays something else? Because that’s what’s ultimately going to happen if they don’t give players such an option. Doesn’t matter which end of the spectrum you opt for, the feel of the game is fundamentally different if you play with Unlimited Skill Uses as opposed to Limited Skill Uses.
But it’s actually pretty easy to set the game up so that both ends of the spectrum are satisfied. Balance it for Tactical Difficulty, so that players using Limited Skill Uses don’t get crucified by the Pandas, but enable players to take the Limiter off if they like Skill Spamming. That way, I get the tight, tactical challenge I’m looking for and Spagman gets the Superman skillfest he was so pleased to learn about:
Same game: different difficulty. Everyone’s happy. Otherwise, either one of me or Spagetman ultimately walks away.
