This is an easy goal in some companies / projects, while in others (usually bigger companies / projects) it's unreasonable and will even be counter productive.
You might need hours of execution time in a test cluster, then need code reviews from several peers (who are busy working on prioritized items), and if your commit is later integrated with commits from other organizations and tested as a whole which results in failures, you put extra load on those who are tasked with finding and sorting out the offending commits.
In principle I do absolutely agree with you that ideally it should be encouraged to spontaneously fix and commit, but in practice "it depends". I've found that larger companies / projects have a certain cadence, and trying to deviate from that cadence too much just results in grinding gears on all levels.
