I don't think the same house rules would be appropriate or welcome for all tables, and would actively detract in many instances. I played in a naval based campaign set inside an archipelago where the DM had Pages of rules for the management and operation of ships and ship fleets, allowing us to build a mercantile empire and engage in high combat on the high seas. It was great. Would I want to hand out those rules to my group with a campaign set in the plains / desert? No, no I would not.
Beyond applicability, there's the matter of tailoring the rules to the Theme. One campaign might be more horror/survival focused, with strict limits on encumbrance, time and rest management, and a healthy dose of the undead at every turn. I've played in such a campaign and it was a Great time. A more standard "monty haul" style campaign where we're hunting and slaying Dragons? The same rule set would be Absolutely Miserable.
Finally, different rules suit different DMs. A DM I had was very good at using a system akin to "destiny dice" where players could tap into their natural heroic destinies and reroll a dice whenever, and the descriptors used for that extra bit of luck / prowess / whatever were great. Then the dice went into a pool for the DM to use for enemies as the fates balanced out. Another DM tried using the same system, but in that campaign, using them didn't feel very good at all, and too often the DM's usage of them got far more mileage than whatever you were trying to do originally, so folks just stopped using them.
I firmly believe that each table, campaign, and DM can and should have its own set of houserules, and attempting to use the same set universally would dilute and weaken the experience provided. Just my 2 cents.
