Like the title says...would you want Apple to release a Macbook Pro with a touchscreen?
It depends on the configuration. If by "Macbook Pro" we mean a traditional laptop form factor, then no. It's pointless.
However, if Apple were to make a fully capable "macbook Pro", but in a tablet computer form factor, then 100%, no brainer it needs a touch screen. And I would carry a mechanical keyboard for sit-down work sessions.
I would buy the second option if it were available... Some might say it is available, but it really isn't. I already tried an ipad pro to use as a hybrid computer/ tablet, but the OS is really holding it back. Some might be offended by this, but those people don't have the same expectation for a computer that I do, apparently.
Probably the biggest reason the iPad failed in the prospective role is that iOS is designed to entertain. Every part is trying to be pretty, and everything it does is a mini performance. I mean, even a simple radio button dances a little jig, and a second radio button can't be hit until the first one finishes...and develpers are not allowed to cut this stuff out! I found that it constantly got in my way, slowing me down....which is the last thing I want from a Computer. Why would I accept always following grandma down mainstreet at 12mph...when I know the speed limit is 30mph? It's okay on occasion, but I don't pay a premium for the experience! Thing is, I had an old and really out dated android tablet, which performed better and faster for my use...
