 Description   

https://github.com/10gen/mongo/blob/d6b3993fcfc68d66fef6a25b268e0146e461857c/src/mongo/db/catalog/README.md?plain=1#LL1121C12-L1122

The index logic is more relaxed because indexes do not go through two-phase drop when running with enableMajorityReadConcern=false

https://github.com/10gen/mongo/blob/d6b3993fcfc68d66fef6a25b268e0146e461857c/src/mongo/db/catalog/README.md?plain=1#LL1321C54-L1323C7

The Flow Control mechanism can be disabled
explicitly via a server parameter and implicitly via setting enableMajorityReadConcern to
false.

Since 5.0 enableMajorityReadConcern is always true.

Refers to unfinished FCV 4.2- / FCV 4.4+ indexes.
