Hey, so 1 year ago they actually released a solution to this exact issue.
In Siege of the Atlas they added an Atlas passive tree which allows you to block content in the endgame, to make it a more focused experience with the systems you want to work with.
For every system you block, it increases the chance of the other systems showing up instead. Additionally, some of the legacy content in the game has been reworked to feel more consistent with modern quality standards.
We’re not at Path of Exile 2 levels of refinement, but Path of Exile 1 is in a great state at the moment.
