To be honest, I have yet to find time to look over the link in detail; there is only so much time in a day

Although this is only speculative on my part, seeing I have not actually read what you talked about. However, most people who use the RPW who use both instruments and not just excusive psalmody; do not actually have a problem with these practices. Provided of course, they are not forced as essential. That could be what Dr. Waldron was referring to as extreme practices?
I do know that CH Spurgeon had no instruments during worship. However, I am not sure if he was rigid on this practice for all true Churches.

The more germane issue, probably had to do with him just not wanting to touch on them. However, knowing Dr. Waldron; it would not surprise me to learn of upgraded editions coming up to this edition. For example; I have his first edition of 'Modern Exposition 1689 Baptist Confession of Faith'. I understand he has made several editions to the book sinse then. Which I understand are just clearer wording and things he may have included because of questions and comments he recieved concerning his other editions.
