If it should be, as it is possible to receive expected result?
As Mike has said - comments are nodes and everything you can do with regular documents you can do with comments as well. This includes the implementation of rules / policies, which adjust the permissions / ownership, or actions that reassign ownership. For a general use case as you indicate, you could define a content rule that does this for all content elements of type "fmost".
What we do in about 80% of customer projects is actually revoke ownership status for most of the business content after creation (comments and such excluded), as ownership and its privileges almost always interfere with role-based permission management which needs to be consistent, intuitive and easy to understand by users.
