No.
Why would they shape psionics to the needs of a campaign that doesn't have psionics from the get-go? Obviously, the campaigns that have the most relevance regarding psionics are the ones where psionics is central, like for example a Dark Sun campaign. People who would use psionics in a campaign where psionics is marginal, shouldn't have strong opinions about psionics.
If one reads the psionics rules from Eldritch Wizardry to PHB3, I think it's obvious that psionics is supposed to be something that the character does, as opposed to magic, which is something they use, they "wield", regardless of the source of magic. That's what makes psionics psionics, and 5e has a mechanics for that right in its core: the ability check.
And probably the most prominent concept in psionics is psionic mastery, which means that you get better and better at certain powers, as opposed to the spell levels of magic. And 5e has the perfect mechanics for that too, which is the proficiency bonus and expertise (double proficiency bonus).
3e and later distorted psionics for the sake of uniformity, but 5e can do better than that. It can recapture the essence of psionics, because it's an incredibly solid and flexible system.
Yes, yes - YES!
