What bottleneck? Let the three fighters handle challenges they way they want.
The bottleneck is, "If you don't want a permenantly crippled character after a fight with a clay golem, you must have someone in the party who can cast
greater restoration."
And part of the issue there is that if that's true, the game doesn't really tell you that explicitly, so you get surprised and blindsided because you didn't read the minds of the game designers.
There is no version of the game that does what you are asking of it. Why have you playing D&D so long if it never ever met your standards?
4e presumed roles and was explicit about it, which would be a fine option for 5e, too (that'd be my second option above). They tell you you shouldn't have three fighters up front. If you went into a fight without a leader in 4e, you knew beforehand what you were getting into, because the game is clear that the four roles 4e has together make for a balanced party. You could still do it, but you KNEW you would have certain consequences, before they became problems. You can go in with your eyes wide open.
If 5e has roles, it doesn't ever mention them as far as I can see. Which means that you don't know you're going to have problems before those problems come up unless you are an excellent prognosticator.

I don't know that "My guess is that the assumed magic item rules will allow basically any party to access
greater restoration" qualifies as having a problem or being dissatisfied. In fact, quite the opposite: it will do what no version of D&D has yet done and finally liberate people to play the classes they want to play rather than the classes that someone MUST play.
My main objection is that I keep getting told that this is fine as it is and that I should accept this even without that because the DM fixes everything and role-less games suck and it is impossible to telegraph roles and none of those things are true.
