Iirc it’s also a prerequisite for full-disk encryption on modern android.

How modern? It's still working on Evolution X with Android 14 (although maybe it needs custom rom support).

It would be a bit less secure since the bootloader itself could be compromised, however (but I wouldn't be concerned about random thieves/snooping in this case).

I did not remember correctly, kind of. From AOSP, Android 7 and later use file-based encryption (FBE) rather then full-disk encryption (FDE). FBE is dependant on verified boot, which itself requires a locked bootloader.

Custom ROMs may have back ported FDE, modified FBE, or implemented their own encryption.
