+	 * Label
+	 *
+	 * The result will be in ucwords() format - first character uppercase, rest lowercase
+	 *
+	 * You might want to do strtoupper() - convert all characters to uppercase
+	 * "HTTP/2 200 Ok" after strtoupper() will be "HTTP/2 200 OK"
+	 *
+	 * It is common for "OK" to have both characters uppercase, 
+	 * and for the other status texts only the first letter of each word uppercase. 
+	 * This is universalized here, so the result will be "Ok" instead of "OK".
+	 *
+	 * If you want to get "OK" without using strtoupper(), 
+	 * just use the literal "OK" instead of self::ok->label()
+	 *
+	 * The uppercase letter on each word makes it easier and faster to read the status text, 
+	 * even if it violates the grammar rules we are accustomed to
+	 *
+	 * I also indignantly conducted a test and tried to use "Early hints" instead of "Early Hints", 
+	 * as well as "Already reported" instead of "Already Reported". 
+	 * The result of my tests was that the readability of such status texts is greatly reduced.
+	 *
+	 * Also note the following:
+	 * 1. "Non-Authoritative Information" -> "Non Authoritative Information"
+	 * 2. "Multi-Status" -> "Multi Status"
+	 * 3. "IM Used" -> "I Am Used"
+	 * 4. "I`m a teapot" -> "I Am A Teapot" (Initially, i wanted to leave it as in honor of tradition, 
+	 * but i decided that this is, first of all, one of our current and working status codes to this day, 
+	 * so it should also be universalized.
+	 * 5. "URI" retains its case because it is an abbreviation.
+	 * 6. "HTTP" retaints its case because it is an abbreviation.
+	 *
+	 * If you do not like my changes, just fork MINIMAL and edit this file. 
+	 * You will be able to get updates without any problems, which probably will not touch this file.
+	 *
+	 * Or you can write a BASH/FISH script with the creation of a link to your version of the file, 
+	 * which will be executed after `composer install`. Of course, you should not do this, 
+	 * but this is a completely working solution that is unlikely to break anything
