Agreed, but that pretty much underlines my point though.

The ecosystem didn't get shattered as a result of me having created 
hidraw.

libfido2 is on pretty much everyone's machine now (at least for those who 
need it), and people are using that all the time to authenticate to 
kernel.org/Google/Okta/whatnot. No workflow got broken in the process.
