It's trivial to circumvent automatic detection

It depends on what you're mimicking. Just registrering the URL scheme? Any app can do that. Mimicking a signed APK with full package name? Can't do that without root and privacy plugins for Magisk.

You can circumvent it using Intent intercept apps, so unless Whatsapp specifically looks for the APK and call it directly (and just use normal intent URL schemes) then you can simply redirect that request.

If it's IP blocked it still won't work, but most aren't

You need to add encryption on top with OTR plugins or equivalent

Or use Matrix where it's on by default
