XP is hard to get on Bedrock Edition

Minecraft Bedrock Edition's XP gain is, to put it nicely, atrocious. The furnace glitches were the only reliable way to get a nice amount of XP. On java there are tons of ways to get reliable on XP such as trading with villagers, using a mob grinder(which on Bedrock doesn't even work half as fast as java) etc. So why not make XP gains and mob spawns similar to that of Java edition?
