When you want to express that something might be wanted or required, there are several ways to convey that idea without using the phrase "it may be desired." Instead, you could say that it could be preferable, advisable, or recommended. Another option is to suggest that it's worth considering or worth exploring. Alternatively, you could indicate that something is necessary, crucial, or indispensable. Depending on the tone and context, you might also use phrases like "it might be fitting," "it could be appropriate," or "it may be wise." The key is to convey the idea that the thing in question is not mandatory but might be helpful or desirable in certain circumstances.
