I'm gonna say "no". The problem is this game attracts people of varying levels of skill and interest, for some simpler forms of gameplay are better for others more complicated forms of play are better.
We accommodate the former in all jobs we fail to accommodate the latter. This is exactly what they've done to healers and tanks in this game where you had jobs that were technical like DRK and AST and used to have more engaging DPS rotations like SCH. As somebody who loved SCH, DRK and AST as they used to be, it's a mentality I can't get behind. I am an advocate for different jobs to represent different difficulties of play. The advantage of having multiple jobs for each role is that you can accommodate more playstyles. SAM I feel exists as a simpler MNK alternative, as an example. Heck they have just made MNK simpler by removing Greased Lightning.
The view I've always had is: if a job doesn't fit your needs try a different job. I can understand changing things if they are broken and complaining if a job has changed so you enjoy it less, but is a job you play.
MNK's positionals to me is a part of the fun. And I've lately picked it up again after its fixes and I think it would be sad to lose positionals on it. I just practice against a training dummy to get used to my positionals and rotations.
From an accessibility point of view, I have a new player in my FC who is currently learning to play MNK, they're new to MMO's too and MNK is their first melee and they struggle at some solo instances in the game and are still learning much of it. They have not felt MNK inaccessible, it has confused them at first but they just wanted to learn to get better at it and not change the job because they enjoy playing it. I sat with them a couple of days ago to help them get into the flow of it against a training dummy and it helped. The game is VERY forgiving, you can screw up your positionals until you get them right long before you get to a point where it's important.
I feel if anything the better solution if accessibility is a concern, the emphasis should be on better tools to learn than making things easier.
