After installing the nRF connect sdk (v2.2.0) via the toolchain manager (v1.2.1) I noticed the installed size of the toolchain was quite big (~ 4.9GB)
Looking into the toolchain directory to see what was installed I noticed the ./usr/local/libexec/git-core directory takes up ~3.2 GB of that space.
A quick md5sum confirmed what I suspected; most of the git sub commands have their own file but are copies of each other (136 files with the same md5 sum, totaling ~3.1 GB) and no soft/hard links are used.
