That's fine.  They will be in /afs because they are mountpoints in
root.afs.  When you try to access them, the cache manager will try
to evaluate the mountpoint, causing an AFSDB lookup for the cell in
question.  So, in this situation you don't need empty CellServDB
entries.

No, there's no dependency; I was similarly confused by your mention
of dynroot in your message.  The two features are fairly independent.

If you are using _both_ dynroot and AFSDB, there is a reason for empty
CellServDB entries: to tell dynroot to make mountpoints for those cells
before you try to access them, but fetch the volume server information
from AFSDB records.  (Same reason as you mention above for non-dynroot
case, except I believe it only applies here and not there.)
