The main drawback is a potential vulnerability to attacks - e.g. a malicious source can now flood your webserver with message up to 2 GB in size and potentially bring it down.

Of course, allowing 2 GB messages also puts some strain on your server in terms of memory consumption, since those messages need to be assembled in memory, in full (unless you use streaming protocols in WCF). If you have 10 clients sending you 2 GB messages, you'll need plenty of RAM on your server! :-)

Other than that, I don't see any real issues.
