Virtual filesystems have always done that in various ways.

Look at the whole discussion about the size of the file. Then look at /proc.

And honestly, eventfs needs to be simplified. It's a mess. It's less
of a mess than it used to be, but people should *NOT* think that it's
a real filesystem.

Don't use some POSIX standard as an expectation for things like /proc,
/sys or tracefs.
