Disabling SSV puts your system security on par with any stock linux distro. Most OSes don’t do a cryptographically verified read only root.

The bigger problem with disabling SSV and making changes to it is entirely practical - any macOS update will overwrite them.

Which can be worked around by writing a provisioning script, but in either case will be a significant headache if one would come to rely on the modifications they were to make to the volume.
