Let's say they did that, does that remove concerns about a 5e or similar?
Good lord, no! They'd still be viewed as not paying enough respect to the prior editions, in some quarters. Or being true to the D&D legacy, or brand, or something else.
I'd be happy if they did it a way I liked, and others would consider that the wrong way to go. There are so many gamers out there, that there are bound to be people not happy with anything WotC does with D&D.
Basically, it's a lose-lose situation for WotC. Except for the PR value of making older editions available. I'd prefer it as POD myself.
