Please add GREtap as it is widely accepted everywhere!

RouterOS has EoIP for that. It is the same thing.

nope ... tried that !
MTik-EoIP and GRETAP make use of different protocol-types
... so ... the feature-request ... is simply a request for a compatibility-flag
.
https://tools.ietf.org/html/rfc2784
.
7.2.  Protocol Types

   GRE uses an ETHER Type for the Protocol Type. New ETHER TYPES are
   assigned by Xerox Systems Institute [RFC1700].

... no wireguard ... in the article ! ... but hopefully well-discussed in this forum soon : )

Ok... it should then be possible to make a selection option in the EoIP interface menu and make it compatible.
A bit of a pity that MikroTik defined their own protocol type for this, while a "standard" type already existed for a long time (it appears).
Of course they now cannot simply change it. But an option should be possible.

Open vSwitch is using GRETAP as a tunneling option ! ... maybe also an option to terminate MTik-wireless-devices over a distributed-foreign network-infrastructure ?!
... with the new hiperf-switches and 10/25G-routers ... ?! that would be "a feature" also for datacenter-like installations !! ... or a door-opener for large scale wireless-rollouts

... sometimes it's just about having my own "Jodeldiplom" ?!

... but opening a platform for a compatibilty is - of course - always a sometimes hard-to-know business-decision ...
I see more options, than contraints for this case

I think it is mostly caused by not knowing the invented protocol already exists and is registered under another protocol number.
I know a similar case in IPIP tunnel which uses IP protocol 4, but another protocol which is exactly the same was registered much later under protocol number 94.
(and fell into disuse after this was uncovered)
