The problem is that I must make these distributions fit within my well established configuration, which is not as easy as installing them on top of a blank one.

Also it might be the fact that vim was never my main programming tool when IDEs were available for the programming task at hand. I debug as much as I write code, so having the debugger in the same context is important to me.

These things may all sound like excuses, but what I'm trying to convey is that vim can be a tool with which someone is proficient, but it's not the main one for writing code, and as soon as friction gets higher, it gets disregarded in favour of something else.
