Yep! Which is why I always am amused by all the "coulda woulda shoulda"s and the despair that comes with it. Because every single one of us can take our coulda woulda shouldas and put them right into the game right now because house rules are a thing. If anyone thinks Hunter's Mark shouldn't have concentration... then just take it out of your game, or else go find a new table for which you can if it matters that much to you.There's no wait, except to see what they've done. The monk class is also set in stone, just like the ranger. Nothing we can say or do will change the books.
But of course, having to house rule means WotC didn't cater to our specific needs, and some people have never been able to handle their way not being the way. A lot of D&D players are self-centered in that way.
