Thanks, but nah.
This would be for setting up how an assortment of devices and
programs were going to interact once they were all connected
and in operation.

Various components would have various timeout values in firmware or system software or a workstation driver, or a config file. Default settings might be fine in most cases, but if you make certain operational choices (like electing to use stronger encryption, which can have much longer key generation times), you might prefer to lengthen some timeouts. However, longer timeouts might collide with other considerations, like your connecting software having its own ideas about how long a transaction should last before deciding that something is wrong. You might have chosen an optional connection strategy that puts some devices in another room or another country, and thereby adds some client-server overhead and some network latency, which forces you to increase certain timeout values, but are other timeouts going to be affected in ways that you (or your third-party applications) don't like?

You might know that some of your systems and components live in a part of the world with choppy network reliability or speed, and the relaxed timeout settings (for some components) might be acceptable to you. Or, you might prefer to run a tighter ship and accept frequent timeouts and necessity for re-issue of certain commands and operations.

You might have chosen to combine certain operations and components in a way that we had not anticipated, for a purpose that we had not envisioned - you want to know what your boundaries are to enact your vision, but you don't want the info in the form of re-entrant word-spaghetti. You want a nice picture.
