New-mailboxexportrequest - no more deletecontent switch?

Question

Trying to mimick a behavior we had in export-mailbox.
new-mailboxexportrequest:
http://technet.microsoft.com/en-us/library/ff607299.aspx
In export-mailbox there was a -deletecontent flag to export and remove the source data.  
It seems in 2010 SP1, this functionality is lost?  Am i missing it?

Search-mailbox has a DeleteContent switch.

Unfortunate that's not a good work around.  Search and MailboxExportRequest do not support the same parameters in which to find emails.  In other words MailboxExportRequest can find and export emails that the search function cannot find.
For example, I can use MailboxExportRequest to find emails that are above 20MB in size and export them.  Search cannot unless someone can explain to me how?
New-MailboxExportRequest -Mailbox *USER* -ContentFilter {Size -gt '20MB'} -FilePath "XXXXX"
The search function does not support SIZE.  So my efforts to find and delete all emails that are above 20MB in size have failed.  My plan was to export/remove them but now I find I can't do that either because MS killed that switch.
