Vivado Timing - write_xdc expands all_registers command

I have the following constraint in my design:

set_false_path -from [get_ports tss_clk] -to [all_registers -edge_triggered]

When I issue a write_xdc for this design, it will expand all_registers so that all cells are now defined. This is very messy.

The workaround is to manually re-write the XDC file.
