Why recover R-134A? Because it's the LAW. As far as reusing it, I think noncondensable contaminants (air) would be a bigger problem than metal contaminants from the old compressor. If the refrigerant is allowed to flow SLOWLY, as a gas, to a chilled recovery container, no metal particles would move with it, and if the refrigerant to be reused is filtered through a molecular sieve filter, any chance of particle contamination is removed.

Here's a site with some discussion of legal and practical aspects of recovering most of the gas yourself, to a chilled container. REMEMBER... go slow, allowing only a slow flow of gas, not a large flow that will cary refrigerant oil and metal particles with it.
