When `Scale=MatchLowercase` is set as a default font option, this scales `mainfont` against the old default, meaning that it resizes whatever is set as the main font to match the metrics of Latin Modern. This can result, for example, in a document set to 12pt appearing in 11pt or 13pt. Setting this option for individual families allows everything to scale against the main font, and permits the user to override the setting if desired. Note that it is not necessary to specify `Ligatures=TeX`, as this is already set by default for the appropriate families. See the `fontspec` manual: <https://ctan.org/pkg/fontspec>.

The manual suggests (¶6.2 Scale) that one could instead do this: \defaultfontfeatures{Scale=MatchLowercase}
\defaultfontfeatures[\rmfamily]{Scale=1}This would theoretically be a touch cleaner, and avoid the potential issue of a user unintentionally disabling scaling by setting other options. In my testing, however, I found that setting the defaults this way actually loads |

OK, great! |

Simplify the approach of #5212, ensuring that `mainfont` is used as the base font for scaling and that LuaLaTeX does not display the mono font with TeX ligatures (as it does not use the `Mapping=tex-ansi` option). With a modified version of `\defaultfontfeatures`, fontspec will continue to report scaling against the old default font in the log, but it nonetheless displays main font at the specified size. Using this rather than setting `Scale=MatchLowercase` for each family individually means that users will not lose scaling when upgrading to the new template if they were using other font options. Scaling can be disabled for an individual family by adding the option `Scale=1` to `sansfontoptions`, `monofontoptions`, etc. Remove the `\setromanfont` command added in #4665, as this is not documented in the fontspec manual and appears to be a deprecated alias for `\setmainfont`. For the release notes, I should also add that one can imitate the previous appearance with `-V mainfontoptions="Scale=MatchLowercase"`.
