I wish I could predefine reference links for use within a project. They would be useful in issue discussions in particular. Some global reference link definitions could even be added automatically by Github, e.g. to typical project documentation files, labels and milestones.

Mentions (using @) and issue IDs (using #) are two types of predefined links that already exist, but that use a prefix syntax on top of standard Markdown. Gitlab supports some additional prefixes, e.g. ~ for labels.
