Today I changed the weight of a custom module of mine in order to change the execution method of hooks (hook_form_alter). I've changed the weight to 1 value heavier than the other module's weight. This seemed the safest thing to do instead of giving it a "random" weight of 100. The original module is a core module (translation) so I hope I didn't break anything.
When adjusting the weight of a module in order to change the execution order of hooks, what are the things to look out for and what are the risks involved?
What I can think of: unwanted behaviour as result of high coupling.
