In case someone’s reading this: the change in this particular version of Renoise was done for a particular reason. I initially thought it was a bug, but it’s not.
The change basically allows tools to attach themselves at an earli(er) stage than what was previously possible, something that was required in order for certain tools (specifically, update checkers) to work.
Hack or not, the solution I proposed above is still working in Renoise 3.1
