I believe so.

I would rather the set failed if the value is too large.  We could expose the
maximum supported number of retries through a #define in the header file.

So, is the proposal to provide a generic set_option call for connection
parameters?  Is there any other parameter than retries?  Does a generic
connection timeout value work for TCP as well?
