WGS84 is earth fixed, which means a feature's coordinates described in 
WGS84 will shift over time, in line with tectonic plate shift.

Yes, WGS84 has had 6 "realisations" to date, but these have been 
refinements to the alignment of the WGS84 ellipsoid. It doesn't account 
for tectonic plate shift.

Storing in the time dependent ITRF or ATRF is a separate issue to what 
is being discussed in this paper.

A static datum can be used still. The important thing is we need to know 
whether we are using static or dynamic and not get them confused.

Yes, very hard problem. One that is very important to solve. Odds of 
success are tough. Challenge accepted. :)
