Google blocking 7zip

[Gmail]

Google scans zip and other archives for particular executable file extensions.

"You can't send or receive the following file types:
.ade, .adp, .bat, .chm, .cmd, .com, .cpl, .exe, .hta, .ins, .isp, .jse, .lib, .lnk, .mde, .msc, .msp, .mst, .pif, .scr, .sct, .shb, .sys, .vb, .vbe, .vbs, .vxd, .wsc, .wsf, .wsh
Messages containing the types of files listed above will be bounced back and returned to the sender automatically. Gmail won't accept these file types even if they're sent in a zipped format. Here are some examples of zipped formats:

.zip, .tar, .tgz, .taz, .z, .gz, .rar"
One assumes this has expanded to .7z files and that the archive contains one of the <dramatic music> banned extensions.

Some time this week, Google started blocking 7zip encrypted archives (.7z).  
You can no longer send or receive emails which contain 7zip encrypted  
attachments nor share them using Google Drive.  

I haven't seen any announcement about this...nor any discussion, but it's  
causing us (as a Google Apps for Education "customer") pain.  

Google are, of course, only doing this for our protection. What other  
reason could there possibly be?
