In reply to Daniel James.

These are the two opinions where the theme directory will never be able to please everyone:

Make it easier to upsell.
Allow themes to recommend or require third party plugins.
This would:
1) Lead to themes being used only for upselling these plugins.
2) Lead to a shorter review process.

*Don't allow upsell. This would:
1) Take away the incentive to submit themes from those who need food on the table.
2) Lead to a longer review process.

Please help me understand what you mean when you say "long winded and backwards review process". And more specifically, what would help you submit themes?
