If this means what I think it does, this is great news. It will make it possible for geotools to choose the "best" transform when multiple ones are available (constrained to the ones we have implemented).
Geotools already use the accuracy information for choosing the most accurate transformation since EPSG database 6.8. However, EPSG database 6.9 would allow to take the geographic area in account, which is currently ignored by Geotools (for example many transformations may be available for the same source and target CRS, but some may be more accurate for a specific area while other transformations may be more accurate for an other area. However, we will need to figure out how to specify the user's preferred area to the EPSG authority factory (there is no API for that right now).
One day I will find time to look at this stuff again (stupid masters thesis...).
I understand very, very, very well... I was in a similar situation less than two years ago.
