Re: HEIC files, why not ?

Given the claimed benefits of HEIC over JPEG, is there any reason not to use them in preference to JPEG/JPG for other than raw images ?
 OK, wider (universal) acceptance of JPG. But anything else ?
 

Licensing and Patents
If BMFF HEIF is used with HEVC encoding, then it is worth noting that HEVC is heavily encumbered with patents, and the Library of Congress does not recommend using such heavily patented formats. The parties holding patents on HEVC include but are not limited to:
     Apple
     Matsushita Electric Industrial Co
     Toshiba Corp.
     Lenovo
The uncertainty of patent encumbering is further strengthened by unclear patent-holders' wordings. Holders of relevant patents stated to the ISO that "the holders of these patent rights have assured the ISO and IEC that they are willing to negotiate licenses under reasonable and non-discriminatory terms." The specification also cautions that "some of the elements . . . may be the subject of patent rights other than those identified."

Patent licensing
Further information: High Efficiency Video Coding § Patent holders
HEIF itself is a container that may not be subject to additional royalty fees for commercial ISOBMFF licensees. However, Nokia also grants its patents on a royalty-free basis for non-commercial purposes.[83] When containing images and image sequences encoded in a particular format (e.g. HEVC or AVC) its use becomes subject to the licensing of patents on the coding format.[84][85][86]
