This can be solved without a changing Git today. You configure the two remotes with different fake host names:

[remote "waterkip"]
  url = git@waterkip.gitlab/waterkip/git.git
[remote "corp"]
  url = git@corp.gitlab/corp/git.git

And set up the real host name and identity file in ~/.ssh/config:

Host waterkip.gitlab
  IdentityFile ~/.ssh/id_ed25519_me
  HostName gitlab.com

Host corp.gitlab
  IdentityFile ~/.ssh/id_ed25519_corporate
  HostName gitlab.com

For this reason, I see little incentive to add complexity to Git that achieves the same.
