Sounds useful indeed. I added `--login no` (the default is yes).

In the document I recommend that publishers of zsh configuration
frameworks (think ohmyzsh, etc.) not zcompile user rc files by
default.

FWIW, I zcompile my own rc files, although I do it in a way that
avoids issues caused by mtime and missing source files (I don't
mention the latter problem in the doc; basically, if you zcompile an
rc file and remove the source, the rc file will still be in effect).
The only downside I get from zcompiling is that aliases get expanded
differently but that's fine with me.
