1. Some people dislike languages with a large instruction set

2. I will propose that programming languages are like anything else created by humans - some parts great, some parts not that great. Furthermore some parts of a language are used more than other parts, it should be hoped that the parts least used in any particular language are parts of that language that are not that great. Given these things it might be reasonable that some time you saw a new version of a language in which they said Feature X really sort of didn't make sense and anyway hardly anyone ever used it so we are removing Feature X. Adjust code accordingly. (probably there should be deprecation stage of a year or so with warnings)

Even human languages aren't not fully used.

There are multiple levels of understanding, regionalisms and specialized technical terms that few get to use.

And that works in language -- its terrible when you are trying to make computers do very specific things in specific scenarios. It leads to hiring nightmares as well. "Oh I write language X in this style, not familiar with your style"
