People change them not because they are not that well thought out, but because every machine is different.
Also people decide that they are going to use different materials like ballscrew instead of leadscrew, and this needs different mountings, they may prefer to use profiled rail rather than bar and so on, also the rockcliff plans are for people on a budget, so most of the time, people upgrade it to be more ridged.

Here's the Rockcliff blurb....

" with our refined plans I have gotten Homemade CNC down to an art, , the plans and instructions we sell today did not appear overnight and have been refined and tweaked over a ten year period, so purchasing our plans today you will feel confident building your DIY CNC router that your finished machine will perform as advertised"

Yet, time & time again...I read of users changing the plans! That would bug me...ie shelling out for the "10 year honed plans"...only to find I have to change/enhance them!

This guy seems to know what he's doing (3 pdf files of his erhmm 'modified' Rockcliff build)...
