New description:

 On Windows, GDAL 3.7.2 gives this

 {{{
 gdalinfo --formats | grep GIF
   GIF -raster- (rwv): Graphics Interchange Format (.gif)
   BIGGIF -raster- (rov): Graphics Interchange Format (.gif)
 }}}

 but on macOS version 3.7.2 the gif format is not listed.   I install gdal
 via

 {{{
 sudo port install gdal +hdf5 +netcdf +openjpeg
 }}}

 and this is the first time I notice lack of GIF support.  Is this an
 omission, policy change, or a new variant I must add (e.g., +gif)?

 I notice my gdalinfo says this

 {{{
 gdalinfo --version
 GDAL 3.7.2, released 2023/09/05 (debug build)
 }}}

 MacOS Ventura (13.5.2)

Comment:

 The gdal port declares a dependency on the giflib port and it uses the
 configure argument `-DGDAL_USE_GIF=ON` so I think the intention was that
 gdal should have gif support. But at configure time it has this somewhat
 conflicting output:

 {{{
 -- Found GIF: /opt/local/lib/libgif.dylib (found version "4.2.3")
 }}}
 {{{
 -- The following OPTIONAL packages have been found:
 }}}
 {{{
  * GIF
    GIF compression library (external)
 }}}
 {{{
 -- The following features have been disabled:
 }}}
 {{{
  * gdal_GIF, Graphics Interchange Format
 }}}
