IGCSEs per se are a lot more flexible about that. You can do any subjects in any combination you like. Its a decision by the school to make English literature compulsory. Home educated kids often do not do it, on the other hand there are are huge number of subjects they can pick from: https://he-exams.fandom.com/wiki/Category:Subjects
British universities do often (usually?) require English language (or an equivalent) and maths (I)GCSEs, as do British employers and further education colleges etc. so its a really bad idea to skip those.
I do think its good to give kids a broad education, and for some it would be good to continue that for longer. For others (like you) its just boring.
I also think there should be more opportunities for adult education, so if you decide later in life that you would like to learn about English literature or physics or whatever you should have a chance to do it. AT the moment in the UK things seem to be going the other way, with an over expansion of universities sucking up money, and further education colleges that used to offer adult education putting the resources into "16 to 18" courses.
