Imagine the market being saturated with all kinds of keyboards in various form factors and layouts and someone holding you accountable for what you're using.
I used to think I can't do without an F-row. Nowadays I use a bunch of 60-ish boards (a Boardwalk, a Lily58, an Elora) and it's all fine. Even back when I was using a 75%, I was used to have e.g. the arrows on IJKL on a layer (of course it doesn't work well for games, but for things like text editing I'd argue it's even better than dedicated keys). In general I'd suggest to everyone to challenge themselves a little bit with things that don't seem good at first but might end up being useful in the long run.
