There's an internal limit that you can tweak:

  :help 'undolevels'

so you can adjust that up/down as you see fit.  You just have to do it
before you make that many changes (so a good candidate for your vimrc)

I don't use them often because my internal/mental clock doesn't sync up
with my editing, but if they help you out, they're good to have in your
tool-belt.

Correct, the :e reloads the buffer (similar to passing a range through
an external filter with `:help :range!` which impacts that range),
losing the marks, jump-points, etc. in that range.  But :w shouldn't
impact those.
