I'm not sure it makes any difference. Once you remove the "lip" by pressing out (and there is a lip/mushroom contrary to what many say here) it theoretically should go in and out easier. IMO it's so hard to push back in though it will probably stay there. And experience backs that up.
I'm sure after dremel it will never be secure again which is why I never do that. Big pain too.
Master link is mostly a matter of conveeeeeeeenience but not so reliable as just pushing the pin back in. I do both depending on time and tools.
