@neauoire I am guessing it really is a new thing. Earliest example I can think of is Java. Sun Microsystems marketed it relentlessly, and it worked for a while.

On the other hand, older languages like C, C++, Common Lisp, and Scheme all went through decades-long standardization processes because several commercially viable implementation already existed and it was beneficial for the corporate stewards of these implementations not to have end-users be locked-in to their competitors.

I strongly prefer using older languages with long-drawn, consensus-based, standardized specifications.
