There is no risk to fix it in 1.17 release.
Feature request? I don't think so. Base stones should be controlled by BIOMES instead of DIMENSIONS.
Not a bug
Report your SEED and your X/Y/Z that you find the floating minecart
See wiki:
The enchantment is chosen randomly with equal chance of any enchantment type occurring (except for Soul Speed) and equal chance to get any level of the enchantment, meaning high-level enchantments are as likely as low-level enchantments. The price in emeralds depends on the enchantment level and "treasure" status. The possible values are 5–19 emeralds for Lvl I, 8–32 for Lvl II, 11–45 for Lvl III, 14–58 for Lvl IV, and 17–71 for Lvl V. For "treasure" enchantments the price is doubled. Note that the cost is capped to 64, meaning that for example Lvl V books truly range from 17–64 emeralds with costs at the upper end of the range being more common.
Dupe

Flying? It's not a bug
You've report this issue in a wrong place.
Wait... 1.17 Release Candidate 2 + Java 8u261? Please report your Minecraft INTERNAL Java version.
You might need to use an upgraded computer
Please summarize your issue clearly in the title
Sculk Sensors may not be supported in 1.17.
Please re-paste your crash report to paste.ubuntu.com. Your crash report is too messy to read.
Is there anything happen in Intergrated Server? Only vanilla Dedicated Server has the bug?
A bugfix example is in [Fabric Mod API|https://hub.fastgit.org/FabricMC/fabric/blob/1.17/fabric-dimensions-v1/src/main/java/net/fabricmc/fabric/mixin/dimension/ServerBugfixMixin.java].
Written in Mixin, with Fabric Yarn mappings (instead of Mojang). Could use Fabric's tiny remapper to handle the mapping issue.
Dude, you are wrong.
I didn't have a code analysis, but I think the positions of the portal blocks have to be hardcoded instead of relating to crystals.
