Yeah... Though I'm sure some of us would know what we were doing with our .htaccess file - most would royally screw something up, that would then force you (webflow staff) to spend time fixing it... which would in turn keep you from developing new features.
Therefore I choose new features over having control of the server environment.
I do sympathize with the SEO ramifications of not doing 301s if you're changing things around - in theory however you could spend the time naming the new (webflow) pages exactly the same and in theory, nothing would change? Though ultimately googles not going to like the IP change - looks phishy ya know... so. well. guess you're still up a creek @grandtheftpixel
