Knuth lived long time ago. Times change. I have a good example why thinking
ahead is good. Have a look in workspaces in v4. The implementation is
everywhere because it is impossible to plug in workspaces to the existing
code easily: it is just not meant for versioning. If version was though as
a future feature, measure could be taken in advance (like having a
"version" unused field in SQL queries). This would simplify the later
implementation of versioning a lot.

Some things must be considered!
