I am not sure I agree with that 100%.  I think as more people/companies 
are moving to e-mail marketing using HTML and XHTML, we need to make 
sure the HTML/XHTML (Gecko in this case) is always kept as up to date as 
possible.  The only way to do that is to keep upgrading Thunderbird in 
connection with Gecko.
