It looks to me like all those options still exist. The documentation still
lists them: https://git-scm.com/docs/git-config

Also:

❯ git clone https://github.com/git/git
❯ cd git/
❯ rg packedGitLimit .
./t/t5301-sliding-window.sh:     git config core.packedGitLimit 512 &&
./t/t5301-sliding-window.sh:     git config core.packedGitLimit 512 &&
./t/t5301-sliding-window.sh:     git config --unset core.packedGitLimit &&
./packfile.c: "pack_report: core.packedGitLimit      = %10" SZ_FMT "\n",
./Documentation/config/core.txt:core.packedGitLimit::
❯ git checkout tags/v2.26.3 -b v2.26.3
❯ rg packedGitLimit .
./t/t5301-sliding-window.sh:     git config core.packedGitLimit 512 &&
./t/t5301-sliding-window.sh:     git config core.packedGitLimit 512 &&
./t/t5301-sliding-window.sh:     git config --unset core.packedGitLimit &&
./packfile.c: "pack_report: core.packedGitLimit      = %10" SZ_FMT "\n",
./Documentation/config/core.txt:core.packedGitLimit::
❯ git checkout tags/v1.6.4.5 -b v1.6.4.5
❯ rg packedGitLimit .
./t/t5301-sliding-window.sh:     git config core.packedGitLimit 512 &&
./t/t5301-sliding-window.sh:     git config core.packedGitLimit 512 &&
./t/t5301-sliding-window.sh:     git config --unset core.packedGitLimit &&
./sha1_file.c: "pack_report: core.packedGitLimit      = %10" SZ_FMT "\n",
./contrib/completion/git-completion.bash: core.packedGitLimit
./Documentation/config.txt:core.packedGitLimit::

So, it looks like not much has changed in that regard.
