Tip, the word is "response", not "responce".

In my view, software architecture should be part of the job of a principal engineer, and the role "software architect" should not exist as a separate thing.

Separately, you would be amazed at how many developers will happily give you code that they wrote a year or more ago, and then not remember their design decisions. So not knowing it inside and out doesn't imply that they are not the author.
