Using a standard link to remove and reattach has no impact on the strength and safety of the chain at that given link. The only problem that can occur is the pin is not seated quite correctly resulting in a stiff link. If this happens just manipulate the link laterally and vertically until the pin seats and pivots easily/smoothly.
Before the "quick" links this is how everyone removed/installed a chain.
^This is TERRIBLE advice^ Narrow (10, 11, and 12 speed) should NEVER have pins pushed out and then back in to join the chain. There is not one manufacturer that recommends this. The outer plates are so thin now and the the pins are flush, it's not possible to safely replace a pin. I've said this before and I'll say it again...if you don't know for sure that your advice is sound, don't post it. It doesn't sound like you're a professional mechanic...if you are maybe you should consider sales.
