You literally, and I mean literally read my mind dear random stranger down to the wording. Micro is definitely underrated.
Micro is a truly goated software. I mean, it can genuinely replace vscode for small scale editing in the context of shopify that the parent comment was referring to.
It also helped me in physics when I had to remember the units like 10^-6 being micro, 10^-9 being nano etc. and the funny thing is that I used to remember it in the start by seeing I am not sure if it was on micro's github or something but it was a comment on how micro has more features than nano and thus it's name.
So like for some time I definitely felt like I was thinking of micro software, then nano and making the feature comparison to find micro to be larger than nano.
Might seem kinda niche but I ABSOLUTELY LOVE MICRO. Its the one software that I install everywhere, even on my android phone by using UserLand[1] with alpine linux.
I tried writing python code on my phone and it was definitely pleasant thanks to micro.
