Any issues with soldering to an RoHS-compliant module with ordinary

Other than making it RoHS non-compliant?

I use 60/40 solder for prototyping, with a mix of RoHS and non-RoHs
components. I haven't had problems -- but I haven't tried to get
anything through environmental cert, either.

At ordinary operating temperatures, no problems.
But SMT parts will tend to dislodge at temps 170C and higher; that is
seen even if one starts with HASL PCB and uses tin-silver solder (paste
or wire).
ANY amount of tin-lead significantly lowers the MP.
