@Michal I understand the wariness of posting on yet another support forum and not hearing anything back, but in this instance, I would not suggest it unless I thought it would help.
It is really an apples-to-oranges comparison of the lack of WireGuard support on a platform vs. a company’s supported product. WireGuard is a project and ultimately it is subject to the whims of its creator. What makes projects like this attractive for *OSS software may not be workable in other instances, commercial or not.
Honestly, I am unable to blame any networking provider for keeping their platform as simple as possible, especially when changes will impact user support.
