Why to remove EZPLOT?

I educate programming and mathematics for many years, MATLAB particularly.

I find that EZPLOT is a wonderful command. It works either for Text-argument or for Syms-argument, and this allowed me to introduce more about Data Types to students. However, recent versions of the MATLAB tell "ezplot is not recommended. Use FPLOT or FIMPLICIT instead".

I wonder why do MathWorks remove EZPLOT, why not to save it in more advanced versions?

I thank in advance for possible answers!

Note that neither of the documentation pages for the ezplot functions (in MATLAB or Symbolic Math Toolbox) say anything about them being removed. In fact, the Compatibility Considerations in the Version History section of the documentation page for the function in MATLAB explicitly state "There are no plans to remove ezplot."

ezplot() was considered to have a lot of overlap with fplot() and fimplicit(), but it had limitations, not having been updated to support some of the newer features. It was getting to be too much work to keep updating ezplot() to emulate things that were already available through fplot() and fimplicit()

I am thankful for all three answers to my question!

However, EZPLOT "was getting to be too much work to keep updating ezplot() to emulate things that were already available through fplot() and fimplicit()" -- I don't think so. I come back to this problem later again.

Thank you!
