It is certainly possible to combine STFT with fast convolution in various ways.
But doing so imposes significant overhead costs and constrains the overall
design in strong ways.
For example, this approach:

I think we're mostly on the same page, Ethan. Though even with STFT-domain
time-variant filtering (such as with noise reduction, or mask-based source
separation) it would seem you could still zero-pad each input frame to
eliminate any issues due to time-aliasing. As you mention (paraphrasing),
