Incomplete sentence noticed; completing it as:

Both me and Chris treat <w> intervals accumulating on a system time since
the beginning of <rtt>, so slow local performance doesn't cause <w> to
cause a backlog.   Even if it did cause a backlog, handling for backlogged
<rtt> (which is the bigger problem and chief cause of lag), that is already
written in the spec (with improved wording), can already adequately handle
this scenario in XEP-0301 clients that used a "wait since last action
element" methodology."

In other words, the problem is already indirectly solved by the Version 0.8
of XEP-0301 (existing section 6.5)
