The fallacy in this argument is the implication that it's difficult or 
even impossible to weatherproof the outside of a splice. Nothing could 
be further from the truth, is spite of some failed "attempts" by some.

I'm not trying to encourage cheaping out on connectors, just trying to 
shed some light....after all, even proper connectors are always 
weatherproofed in commercial installs. The VERY same weatherproofing 
techniques will GUARANTEE a hermetic seal on homemade connections just 
the same.
