Yes, and it's a pretty terrible one. It normalizes language used by a... let's say very controversial figure. Transplanting it to contexts where it might make some sense serves to validate the original use.
If someone critical of the US President "ironically" uses the phrase, as in "Foo is slow, so let's make Foo fast again", they inadvertently construct or reinforce a notion of "America was not great, which is why we needed to make America great again" -- something they might not agree with. Also, it's just constantly giving more exposure to someone who already has way too much of it. They would be running a political figure's propaganda for them. Many people will want to do that, but also very many people would not want to do it and should think a bit about a slogan's context before adopting it.
(I'm aware that others across the US political spectrum have used the phrase in the past. It doesn't matter, it is currently very strongly associated with one person.)
What would be a terse way to (not ironically) express the notion that some thing X has gotten worse over time, and that we want to return it to a state where it is objectively the same or better than it was before?
Or maybe "Getting LLVM to compile as fast as it used to."
And 10 years ago I would have maybe suggested "Make LLVM fast again" but now it has become so strongly associated with a political party that I avoid it, precisely to avoid turning technical writings into political flamewars.
I mean, America does have serious issues that make it not nearly great as it could be.
Trump doesn't seem to be addressing those issues, but there is nothing wrong with the implication that America has lost some of its lustre.
Just like the author of a post called "Make LLVM Fast Again" may have identified a problem without actually fixing it. The first step to improvement is identifying the problem. LLVM has problems, America has problems. Seems fine to me.
