Yes it is implied by Guideline 4.1 Compatible: Maximize compatibility with current and future user agents, including assistive technologies.

However, that is a guideline  - not a requirement.   It is, as David points out - a general goal.  But Guidelines are not requirements of WCAG.   They are goals - that are not achievable for all content for all users - but do help you to understand what the Success Criteria are striving toward.   

Only the success criteria are requirements  (and the conformance requirements) .

PS it is also pointed to by Principle 4: Robust - Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.
But again this is a general principle  and not a requirement.
