Indeed, Ed. No issues thus far. I upgraded my local dev environment to 5.4.20-1+reiser4 on February 15, 2020; in such environment I have built several PHP-7.3 iterations and I also built kernel 5.5.5-1+reiser4 yesterday. Additionally, replaced 5.4.20-1+reiser4 cloud flavour in a Google Compute Engine (GCE) customized Zstd transparent compression instance -- which hosts multiple PHP and Ruby applications and functions as a media / web server, as well -- without issues thus far.
Best Professional Regards.
