look like template-tag-arguments also could be dropped, I will do it tomorrow

looks like quite some effort for very little size gain ... this project is maintainance only, I am not willing to receive new issues and tackle these because we removed 0.3K minzipped from an already light package that uses modern standars out of feature detection when possible, hence it already performs at its best.

I though that the project is maintains and regarding your message that you don't have a free time - #413 (comment)
I am ok if you close PR.

This project is in maintenance mode, meaning:

• obvious bugs will be fixed
• that's it

Changing or removing support for legacy browsers would require a major and a potential list of future issues to deal with due people not expecting the dropped support or having some slightly difference in the execution or maybe something was already fixed and using the standard without features detection broke things or maybe somebody is stuck in old TypeScript and removing the fix around templates break.

All of this for what ... 0.3K or less once minified? Hard pass, thanks!
