You seem to mean by this that you have a last level, the one
indexed by w.

I can drop the "informally": A tree with w levels! What is the problem

Nothing at all.

However, you have a huge problem if you are saying there
is a level that has index w.

It may make perfectly good sense, depending on your definition of
"tree".

Just one of the many problems this creates for you:
what is the index of the level immediately before level w?

Depending on your definition of "tree", it can happen that "level
immediately before" need not be defined.
