Is it safe to remount the filesystem root / as read-write?

To clarify: I know that basically any root access is unsafe. But I'm asking ***only*** about the remount command itself, not about what can happen after. I want to execute as root something like:

mount -o rw,remount /

Can this particular command or its equivalent theoretically break something (especially my data or even the whole OS) or I only need to be careful after the execution? P.S. I use *Termux* as terminal emulator and *KernelSU* as root solution, but I don't think these things matter
