Fil-C is going to usually be a huge perf regression right? Sometimes I won't care, sometimes I will and this will vary between users with only some commonality.

I think any software on the "most people are annoyed" list will get a rewrite. All the tools where people cared specifically about perf anyway are already rewritten or being rewritten because there are so many performance opportunities. The out-of-box grep sucks compared to ripgrep for example.

It will suck to be someone with no programming ability for whom a tool most people aren't annoyed by is too slow with Fil-C for their niche use. But that's not so different from how it sucks when your local government forgets deaf people exist, or that time we made everything use touch screens so if your fingers don't "work" on a touch screen now you're crippled with no warning.
