Perhaps on NetBSD/alpha. On NetBSD i386 and x86_64 they are not, see https://mail-index.netbsd.org/pkgsrc-bulk/2020/06/10/msg019074.html (pkgsrc-2020Q1 x86_64) https://mail-index.netbsd.org/pkgsrc-bulk/2020/06/09/msg019073.html (pkgsrc-current x86_64) https://mail-index.netbsd.org/pkgsrc-bulk/2020/06/10/msg019077.html (pkgsrc-2020Q1 i386)
pkgsrc from 6-June works, but pkgsrc from today doesn't. This happens on all architectures.
