    sets of resource quantities

    at least

    Ditto comment in earlier review, no need for the quantities namespace

    Is there a way (e.g. benchmark) to check that we didn't make this contains slower?

<https://reviews.apache.org/r/69603/#comment297042>

    Based on my other comment, more explanation is needed here about what this is for and
whether it's accomplishing it.

Lines 753-754 (original), 745-746 (patched)
<https://reviews.apache.org/r/69603/#comment297041>

    We call these "first class" rather than "common", but why do you want this logic?
    
    Maybe you intended to warn about potentially "scarce" (i.e. "non-ubiquitous") resources
being used in the flag? Like "gpus"? Or "someCustomResourceOnlyOnSomeMachines"?

    Maybe you can line up these contains comments to make it a bit more readable?
