questions about inconsistencies in Slur and PhrasingSlur

[Mark Polesky]

1) Slur has a default line-thickness property, so why doesn't PhrasingSlur?

2) If Slur.thickness = 1.2, why does PhrasingSlur.thickness = 1.1?

Are these oversights?  Based on my understanding of classical engraving,
regular slurs and phrasing slurs would have been engraved using the same
tool.  I'd vote for making these props consistent between the two grobs.
Should I do that?  Or am I missing something?

Thanks.
