···
+Starting from go1.14, go verifes that vendor/modules.txt matches the requirements
+and replacements listed in the main module go.mod file, and it is a hard failure if
+vendor/modules.txt is missing.
+
+Relax module consistency checks and switch back to pre go1.14 behaviour if
+vendor/modules.txt is missing regardless of go version requirement in go.mod.
+
+This has been ported from FreeBSD: https://reviews.freebsd.org/D24122
+See https://github.com/golang/go/issues/37948 for discussion.
