Apple uses the standard USB-PD standard for all existing wired USB-C charging, uses the QI standard for wireless, and directly contributed their magsafe technology to the next generation of the QI wireless standard, so there's no reason to think they will make iPhone wireless charging proprietary.
Furthermore, they'll be shooting themselves in the foot. The EU is already curtailing wireless charging lock-in, by mandating Qi charging support. A tailor-made solution might have a higher speed, but as technologies improve, the "harmonised interoperability" will be bumped up by the EU parliament.
Lastly, this legislation doesn't seem aimed at just the EU. My legalese isn't all that great, but it seems they're highly encouraging members of the EEA (non-EU) to adopt similar legislation too.
