No risk no fun ...
In the old Amigadays I soldered everything round my machines ( A1000 with 2MB kick, A4000 Desktop with 5th slot ...). With the years I even got better ... just the BGA is still a NoGO.

Of course, it would be nice, if bplan quickly fixed the OF, MorphOS 1.5 (or 2.0) was ready ... but years have passed and the reality is still MorphOS 1.45 and slight buggy PEG2 and Peg1 OF ......
