Why it is not possible to use 'SHA512' hash for rootpw(root password) in Satellite kickstart profile ?

Issue

• Root password(rootpw) of the hash is changed back to MD5 hash upon commit on Satellite Kickstart.

• On a Satellite 5.3 and 5.4, if in a kickstart profile setting auth --passalgo=sha512 --enableshadow but disable MD5 then change the value of rootpw to SHA512 hash, the hash is changed back to MD5 hash upon commit.

• Changing rootpw to SHA512 using Satellite API kickstart.profile.setAdvancedOptions does not work.
