Plenty of people (and agents), me included, use commit-and-push as an equivalent to "Save". You spill coffee on a day of unpushed work once, you stop caring about dogma like "commits should be finished, testable, reviewable units of work with discrete, human-readable descriptions" and start treating your Git remote as your backup system.

Besides, you can push amends to your branch, or describe/review/squash your changes at PR merge time anyway, so what's the harm of a zillion pushes? Other than "GitHub engineers have to invent a novel database", that is. But that's probably enrichment for them.
