Restore deprecated constructor for binary compatibility support

Code that compiles against the non-deprecated version does not see the
new constructor that has been introduced. As such, there is no way for
them to migrate to it without resorting to reflection.

This commit restores the deprecated constructor so that people can try
the latest version more easily.

Closes gh-34238
