I did one the other day on an old style POE.  I managed to cut the wires 
without blowing it up, but the crimp did it in.

Gotta be careful.  If you cut across all the pairs at the same
time, you
will definitely short the output of the POE injector. Newer
ones might
be able to deal with that as long as the short doesn't last
too long.

However, you can usually cut each color separately without
doing any
harm.  The challenge is getting them the same length.

then do the splice/work/end on it, then plug it back in,

The risk is dropping 24VDC across the Ethernet…

 

The power supply might be able to take it but the NIC chip might not.

 

Plastic crimps just have a much shorter lifespan on the dies, but if they are 
only used to crimp hot connections they should last a while

It's not worth the risk of damaging equipment IMO.

If this is a common concern, why not have the cable run stop at an 
outdoor box before going in to the home? UBNT has a solution for this, I 
know others do as well.

If you are careful when you open the jacket and only cut the blue, then
brown pair and don't short them it can be done. 

Problem is when you re-crimp you short the PoE to the Ethernet and there is
no way to avoid that unless you are punching it down or using the crimp
caps.

In general I would do it in a pinch, but I don't trust installers to do
it...
