Removal of copyright years

Dear copyright experts,

recently the upstream authors of one of the packages I (co-)maintain 
adjusted the copyright statements of the project on the occasion of its 
integration into the High Performance Software Foundation.

As part of this change copyright years were removed from the copyright 
notice (see [0]). According to [1] this happened because the upstream 
authors "got tired of updating those years and it matches the LF 
recommendation" (where "LF recommendation" is a link to [2]).

I wonder what are the implications of this removal on the corresponding 
Debian package [3] and its copyright file.

Best regards

Peter
