In similar projects, instead of going really low level with using single file
and rewriting blocks (which is often incompatible with muxed formats), we
resorted with fixed size fragments (using splitmuxsink). We used the "format-
location" signal to implement custom formatting of the file names (spreading
into multiple directories and using date for file names) and also as a trigger
for too ancient recording removal.

We could then playback the files as if it was just 1 large recording using
splitmuxsrc, of course with a wrapper that implement the same format-location
signal.
