What I meant is that xdph is literally a fork of xdpw

I get the sentiment, but to be fair you can use many parts of xdg-desktop-portal-(kde/gnome/gtk) on hyprland/wlroots as well. I don't think it's the job of this specific package to denote that compatibility unless all packages of this type can agree on a convention.

I would say just providing the impl will be enough.

This package does technically provide xdpw though, as xdph can be used in any wlroots based compositor without issue and will act the same way xdpw would. Not aure it makes sense to remove that statement. Sure though, I suppose this could be removed as providing the impl should be enough.

Let me know what I should do

It seems like pacman has no way to ignore the conflict, and they recommend fixing the packages above all else (https://bbs.archlinux.org/viewtopic.php?id=247171). I don't know what the solution would be either, unfortunately. So far I've been manually editing the PKGBUILD to remove the provides statement but this is frustrating, especially because this package locks up any -Syu system updates I do.

It's still conflicting with xdg-desktop-portal-wlr-git. I was assuming because this package provides xdg-desktop-portal-wlr and xdg-desktop-portal-wlr-git conflicts with that.
