Enhance /fill...replace command to preserve unspecified blockstates

Currently,

/fill <fromXYZ> <toXYZ> <target> replace [replacement]

If you don't specify specific blockstates for the target, it will target all matching blocks irrespective of their blockstates, and replace all variations with the specified replacement. This truncates all target blockstates with the replacement ones, including causing blockstate deletion if not specifying any replacement blockstates.

But what if you do want to match all variations, but replace only their material and want to preserve existing blockstate( value)s instead of completely overwriting them all?

I suggest to add another optional keyword at the end of the command such as "preserved", which if specified adds the effect of all blockstates and their values not specified by the replacement to be maintained for each replacement block that supports the blockstate/value pair. Such that:

/fill <fromXYZ> <toXYZ> stone_brick_stairs[waterlogged=true] replace stone_stairs[waterlogged=true] preserved

Would replace all orientations of stone stairs that are waterlogged with their waterlogged stone brick counterpart, preserving any existing "facing", "shape" and "half" blockstates in the targets. To accomplish this currently, a different command needs to be used for each and every possible value of each of those blockstates that you want to target at once. Which can be a total of 40 commands in this case of specifying the waterlogged one. With just "preserved" added to the command it can be reduced to 1 command.

  Other examples that explain how this command would work:

  /fill <fromXYZ> <toXYZ> stone_stairs[waterlogged=true] replace stone_stairs[half=bottom] preserved

  This would replace all stone stairs that are in the bottom half of their blockspace, regardless of whichever shape or facing blockstate they may have, and only affect their waterlogged blockstate for all of those.

   

  /fill <fromXYZ> <toXYZ> stone_stairs[half=bottom] replace stone_stairs[half=top,waterlogged=true] preserved

  This would do the same as above example but only for the slabs in the top of their blockspace, and not just turn them waterlogged but also position them in the bottom half, all while preserving the not mentioned shape and facing blockstates.

   

  /fill <fromXYZ> <toXYZ> stone_brick_stairs[half=bottom] replace stone_stairs[half=bottom] preserved

  This would replace all types of stone stairs that are in the bottom half of their blockspace with their stone brick counterpart, while not changing the orientation and not adding/removing the waterlogged state on any of them.

  Love this! I think it's much more common to want to change the material of things, so making that the default would be so useful! Using the blockstate identifiers would still be able to change the specific orientation if you wanted, but it wouldn't be the default

  This seems like such a no-brainer to me. It would save me so much time and headache.
