Considering that it is all supposed to be backwards compatible, from what I understand, I would think I could still choose the subclass regardless of 2024 or 2014.
The promise of backwards compatibility was made by Wizards of the Coast about their own IP, it wasn't a promise made for or about the IPs of others. Some 3PP or partners may not want their content to be compatible with 2024 rules for whatever reason.
So, if I play the tabletop version I can make an echo knight using 2024 rules, but for some very odd reason this choice is not given to me using the convenience of D&D Beyond. It seams strange to remove those items from the list of choices when I have 2014 checked along side 2024. I do not see a legal reason for it. Just populate it into the list. Seems simple to me.
I'm not sure a comparison between the legal arrangement you have with 3rd party publishers (none) and those between WotC and 3rd party publishers. Just because you can do something at your table, that doesn't mean WotC can do it on their digital platform
