Do I gain anything from explicitly writing this with d-flip flops (like you did in your ByteBlaster code) instead of a vector? I must be missing something important.

The recommendation was more to start using
components, rather than writing things inline. A synchronizer is a useful component. You can add generics to indicate how many stages of DFFs to use and whether to power-on high or low.
When you start using components in your source, it also becomes easier to read, since you start to see the 'big-picture' rather than a huge number of VHDL signal names that have slight variations. Eg. The input spi_clk becomes spi_clk_sync once synchronized.
