As per LKK’s answer, you could nip this in the bud and get it to zero if you are able to split up this module. It’s hard to know without seeing it, but I’m guessing it has dependencies on modules from both MyApp and MyAppWeb and I’d even wager that modules in the MyApp boundary are also calling functions from it. This is the most common cause of nasty compile deps in my experience. If you can split it up so that module dependencies are always flowing MyApp → MyAppWeb you shouldn’t have any issues. I’m just guessing at your situation, though.
