Hi,
I have been using dcraw a lot and now trying LibRaw because I have a camer that uses cr3 files. In LibRaw I am missing two main featerus that used to be pasrt of DcRaw.
1. The possibility to keep original capture date when converting to tiff (-z in DcRaw)
2. The option to assign a camera icc profile after linear conversion ( -p )
Have those options been removed for a specifif reason?
1) Yes, there is no code that
1) Yes, there is no code that adjusts timestamps
2) dcraw's -p camera-profile is not 'assign camera profile', but covert from camera profile to output profile. This option is supported by dcraw_emu if compiled with LCMS support

why
Thanks for your reply. But the -z switch to keep capture date was in dcraw. Why is not in libraw anymore. What is the logic behind that?

We will be glad to accept your patch that will support the functionality you need.

-p switch in dcraw
The -p switch in dcraw was to apply a camera icc profile or embed
(using github copy of dcraw.c
(using github copy of dcraw.c 1.478 to highlight lines)
-p switch sets cam_profile variable: https://github.com/ncruces/dcraw/blob/master/dcraw.c#L10187
The only code line where this variable is used is apply_profile call: https://github.com/ncruces/dcraw/blob/master/dcraw.c#L10458
The apply_profile function applies the profile, not embed it: https://github.com/ncruces/dcraw/blob/master/dcraw.c#L9651

Solved it with Powershell script
I made a powershell script to convert all raw files with dcraw-emu and use exiftool to set original capture date and assign camera icc profile to the tiff.
