Sometimes? I’m no expert, but I’m pretty sure these games were generally not built with a hefty bible full of inviolable lore. Plot and continuity errors are common enough to show that.
Some people are very invested in making sense of things that just don’t have a ton of intention and meaning behind them.
The developers of the Zelda series always tried to make new games fit the previous one's lore.
The devs themselves put a ton of effort on making these games kinda fit with each other at the time they were making each new installment, it wasn't a retroactive thing. They just weren't super pedantic about it until the official timeline came out.
The timeline's always been a mess, but it has been something that has been given serious thought since at least the late 90s.

That's not to say that there is a capital C canon that constrains all subsequent installments to be 100% self consistent. They seem to enjoy the freedom of being able to change things to fit their vision for the next installment. I just don't think it's correct to say there's no thought at all put into the head revision of the canon.
