I just heard this phrase, and I'm so happy because I've needed a word for it. People who do this annoy me so much. Like with EVs especially. "Well we should be using mass transit_." Yes, we should, but that will take a very long time. Let's take a good solution now, which is better than the bad solution that is currently being used, and we will continue to build and push for the perfect solution at the same time.
Strive for perfect, but accept a good solution in the meantime.
