Why is it recommended to split a large document into several parts and include them with \include
? Is it only a relic of the past times when computers and LaTeX compilers were slower, or is it still up-to-date? What are the pros and cons of this practice, also in terms of interaction with other external tools (version control, find/replace, et cetera)?
Motivation: I've found a recent discussion that mentions this practice ( Writing and Managing Thesis in LaTeX, Everyday LaTeX and workflow?), as well as a comment that criticizes it in an answer to Everyday LaTeX and workflow?. A couple of months ago, I asked the same question in a comment to Techniques and packages to keep up with good practices, but it's probably better to ask this here again as a "real question".
