Apps on my mobile phone stop working when my operating system gets updated. If nobody takes care of these programs they start to die. Not saying that it's good, but that's just how it is. You cannot take all responsibility away from the user. If they are able to update their Heroes/ERA to use the newest mods they should also be able to inform themselves about possible conflicts or ways to solve it. If people would post more of these conflicts on heroes community or on heroes3.5 we could take care of, but I don't see many complaints.
Idea: forward these issues to us on Discord, that will probably speed up the process.

Second: In a year from now. People will be using ERA 3. And they will still download these mods and complain.
Conclusion: If the old mods don't get updated the situation will not change.
Third: I think the fixing of these mods is not so hard. Mostly it will be a little correction and everything will work.

If we start the process of fixing now or on 6 months doesn't matter. In my opinion, these fixes should be made on the base of ERA 3, everything else will just delay the core problem. Starting to deliver ERA 2.46 to play older mods might be a temporary solution, but it will just get worse in the future.

We can create a forum entry where mods are listed that lost compatibility due to the new ERA, together with the specific reports. The list will not be endless. Everybody who is in the mood can work on it. After some time we should be able the have all mods that Sal has on its google drive link are updated, or at least the ones which are worth it.
