I think he's rather refering to the fact that his remove comamnd might be 
broken. So after removing the package from the profile WPKG tries to remove it 
using the given command which is not working. So WPKG will re-try to remove it 
over and over again.

This is exactly the use-case I have implemented the upgrade-before-remove 
functionality.

So he can simply increment the revision and fix the broken remove command. The 
updated package might even have no upgrade commands.
On next WPKG run WPKG will upgrade the package first to the latest package 
revision. If upgrade is successful, then WPKG will use the new (fixed) package 
for removal and properly remove the package.

So everything Mikhail has to do is to fix the package (fix remove commands) and 
increment the package revision. He just needs to make sure the upgrade commands 
either do not execute anything or do work properly even if no real upgrade is 
performed (for MSI installers this is not an issue).
