So we're talking about a [200ms ; 120s] range no matter what.

Why is 200ms a valid lower bound for initRTO? I'm aware of
measurements that 1s is save for Internet, but I don't know of any
studies that 200ms is save...

The constants that are quoted aren't specific to the initRTO.  They're
used to bound the RTO as it gets adjusted during the TCP session.  See
`tcp_set_rto' in tcp_input.c for reference.
