[Feature] Support for NativePHP

[tabacitu]

We DEFINITELY should support it. Can't wait to use this for clients - https://nativephp.com/

Status: @phpfour has tried it:

Hey guys.

Doing a quick cleanup here.

Thanks for your effort @phpfour I think it could be something nice to have, let's see how things evolve in the future. 1 year after this PR and NativePHP still in alpha.

But realistically, even if they launched the stable version today, I don't think we would be spending resources on something nobody ever asked for.

I am going to close this, but if you work on this and there is something we can/need to do in Backpack to support it, let us know, you know where to find me ;)

Cheers
