I had a 2017 MBP that I just replaced with a M2 and I had a similar experience. There were some annoyances with the space bar, or the t, or randomly repeating characters... over five years. I never had a key completely go out and things would fix themselves; it became an ongoing joke about the self-healing keyboard. Though it never should have been a joke to begin with. If it would have been my primary machine it would not have been acceptable. Some people went through multiple keyboards and periods of downtime so we definitely got off easy.
